Moses Judah Folkman (February 24, 1933 – January 14, 2008) was an American medical scientist best known for his research on tumor angiogenesis, the process by which a tumor attracts blood vessels to nourish itself and sustain its existence. He founded the field of angiogenesis research, which has led to the discovery of a number of therapies based on inhibiting or stimulating neovascularization.

Early life

Born in 1933 in Cleveland, Ohio, Judah Folkman accompanied his father, a rabbi, on visits to hospital patients. By age seven, he knew he wanted to be a doctor rather than follow in his father's footsteps, so he could offer cures in addition to comfort. His father replied, "In that case, you can be a rabbi-like doctor," words his son took to heart.^[1]

Folkman graduated from The Ohio State University in 1953, and then Harvard Medical School^[2] in 1957. While still a student at Harvard Medical School, he developed one of the first pacemakers^[3]. After his graduation, he did his surgical residency at Massachusetts General Hospital, where he rose to the rank of Chief Resident in Surgery. During this time, Folkman worked on liver cancer and atrio-pacemakers.

Between 1960 and 1962, Folkman served in the United States Navy as a lieutenant, where he studied blood vessel growth at the National Naval Medical Center in Bethesda, Maryland. During his service in the U.S. Navy, Folkman invented an implantable device for timed drug release ^[4] and donated it patent-free to the World Population Council. It contributed to what is now known as Norplant.^{[3] [5]}

Work on angiogenesis

In 1971, he reported in the New England Journal of Medicine that all cancer tumors are angiogenesis-dependent. If a tumor could be stopped from growing its own blood supply, he surmised, it would wither and die. Though his hypothesis was initially disregarded by most experts in the field, Folkman persisted with his research.

After more than a decade, his theory became widely accepted and is now being exploited in the treatment of a growing number of diseases, including blindness caused by macular degeneration^[6].

Folkman pioneered the use of interferon to heal hemangiomas, growths that often threaten the lives of infants. His research has led to the development of progressively more potent compounds, such as angiostatin, endostatin, vasculostatin, caplostatin and lodamin, that have successfully halted the growth of tumors in laboratory mice^[7]. Two angiogenesis inhibitors based on Dr. Folkman’s hypothesis and developed by Genentech, Lucentis and Avastin, are now FDA-approved for use in age-related macular degeneration and some metastatic cancers respectively.^[8]

Over 50 angiogenesis inhibitors — including endostatin, angiostatin, 2ME2 (Panzem), and a thrombospondin analogue — are in clinical trials today^[when?] for cancer treatment, including a number with unanticipated anti-angiogenic effects. These include the anti-inflammatory drug celecoxib (Celebrex); rosiglitazone (Avandia), a drug commonly used to treat Type 2 diabetes; doxycycline, a common antibiotic; and some cancer drugs that also have other mechanisms of action, including Erbitux, Herceptin, Velcade and Tarceva. Even some conventional chemotherapy drugs have demonstrated anti-angiogenic effects when given frequently in smaller doses (see Anti-Angiogenic Chemotherapy below). Folkman envisioned that someday, angiogenesis inhibitors would be used together or in combination with conventional anticancer therapies such as chemotherapy, radiotherapy, immunotherapy, gene therapy, or vaccine therapy.^[9]

Scientific legacy

Folkman was appointed the Julia Dyckman Andrus Professor of Pediatric Surgery at Harvard Medical School in 1968, where he was also Professor of Cell Biology. He was the youngest full Professor at Harvard Medical School in history. In addition to directing the Children's Hospital Boston Surgical Research Laboratories, which grew to become the Vascular Biology Program, for nearly four decades, he was the Scientific Director of the hospital's Vascular Anomalies Center. A revered figure at the hospital and throughout the world, Folkman's insights informed many active research efforts outside the field of vascular biology. He constantly initiated new collaborations to study a number of varied disorders, including hydrocephalus and hemorrhages in the brains and eyes of premature infants. His presentations consistently drew standing-room-only audiences.

Folkman was a member of the National Academy of Sciences, the Institute of Medicine, the National Academy of Arts and Sciences, and the American Philosophical Society, among others. He was the author of some 400 papers and more than 100 book chapters and monographs and received scores of United States awards and honors for his research as well as numerous international awards, including Canada's Gairdner Foundation International Award, Israel's Wolf Foundation Prize in Medicine, Germany's Ernst Schering Prize, the Italian Association of Cancer Research in Rome's Gold Medal, the United Kingdom Society for Endocrinology's Dale Medal,Prince of Austurius Award and Switzerland's Dr. Josef Steiner Cancer Research Award. In 2006, Folkman was one of seven people appointed by President Bush to the National Cancer Advisory Board of the National Institutes of Health.

Folkman's scientific accomplishments included founding a new field of biology and devising a novel approach to understanding and treating many diseases, including cancer. He mentored an entire generation of world-class scientists and clinicians throughout the world. This accomplishment, along with his generous collaborative spirit, has resulted in the continued study of angiogenesis in hundreds of laboratories worldwide.

Death

Folkman died in Denver^[10] on January 14, 2008^[11] en route to deliver the 2008 Keynote Address at the Keystone Symposium (Molecular Mechanisms of Angiogenesis in Development and Disease) in Vancouver, British Columbia, one of the hundreds of lectures that he delivered at conferences and meetings around the world.

He is survived by his wife, Paula, two daughters, and a granddaughter.^[12]
